    • 10/10 Car Seat
Color: Seascape Style: Original
Review Image by Sarah Milling Sarah Milling
This car seat is so nice! The install is very easy, how to adjust height is easy! I got it cause my little man hated the infant bucket seat and he loved this car seat as it seems to be more solid, more comfortable (padding is nice), and allows him to sit up straight better. 10/10! Also, I was worried it wouldn't fit well into a 2014 Toyota Corolla and it fits perfectly! 😁 ... show more

    • MAXI COSI PRIA CARSEAT (HIGHLY RECOMMEND) ⭐️⭐️⭐️⭐️⭐️
MAXI COSI PRIA CAR SEAT (INFANT & TODDLER) ⭐️⭐️⭐️⭐️⭐️ 5 STARS OUT OF 5 STARS MY FAMILY LOVES THIS CAR SEAT & CAN’T RECOMMEND IT ENOUGH. WE’VE ORDERED THREE OF THEM NOW FOR ALL OF OUR CHILDREN AND ARE EXTREMELY PLEASED! THE DESIGN IS MORE BULKY THAN MANY OTHER CAR SEATS BUT IT FEELS MORE SECURE AND COMFORTABLE AND PADDED FOR THE SEATED CHILD. INITIAL INSTALLATION IS A BIT TOUGH AND CONFUSING. THE CAR SEAT LATCHES THOUGH THE SEAT BELT SYSTEM IN THE CAR ITSELF, SO MANEUVERING THE CARS EXISTING SEATBELT THROUGH THE NECESSARY LATCHES IN THE CARSEAT CAN GET TRICKY, AT FIRST, KNOWING WHERE EACH STRAP SHOULD GO. ALSO, IF YOU DON’T HAVE SMALL HANDS THREADING THE SEATBELT STRAP PROPERLY IS DIFFICULT TO MANEUVER. THERE ARE TWO CUP HOLDERS INCLUDED WHICH SIMPLY TWIST IN TO CLASP. THE CUP HOLDER CUP ITSELF CAN BE REMOVED EASILY BY A CHILD BUT ARE QUICK AND EASY TO RESET. THIS CARSEAT COMES WITH PADDING AND INFANT INSERT PIECES TO ACCOMMODATE CHILDREN OF ALL AGES AND SIZES. EACH INSERT PIECE IS EASILY INSTALLED AND CAN BE SIMPLY REMOVED ONCE OUTGROWN. WE’VE USED THIS CARSEAT BOTH FORWARD FACING AND REAR-FACING AS ITS DESIGN IS MADE TO GROW WITH THE CHILD. ONE PROBLEM WE ENCOUNTERED WAS HAVING ENOUGH SPACE FOR THE DRIVER TO EXTEND THEIR SEAT BACK WITH THE CARSEAT PLACED DIRECTLY BEHIND THEM, WHEN REAR FACING. MEANING, AS A TALL PERSON, I WAS NOT ABLE TO HAVE MY DRIVERS SEAT AS FAR-BACK AS I NEEDED IT WHILE ALSO HAVING A REAR-FACING CARSEAT DIRECTLY BEHIND ME. WE HAD TO PREMATURELY FRONT FACE THE CARSEAT DIRECTLY BEHIND THE DRIVER TO HAVE ENOUGH SPACE TO COMFORTABLY DRIVE. (I AM 5’ 11” TALL AND THIS WAS IN A JEEP GRAND CHEROKEE— JUST FOR CAR AND DRIVER SIZE REFERENCE.) ... show more

    • Huge Upgrade from Safety 1st – Maxi-Cosi Pria is a Game Changer!
Review Image by Bernaa💕 Bernaa💕
After using the Safety 1st car seat for years, we finally switched to the Maxi-Cosi Pria for our 4-year-old—and I honestly wish we had done it sooner. The difference between the two is incredible. With the Safety 1st, my daughter constantly complained it was “not so comfy.” On longer drives, she would be fussy and miserable. The seat never felt stable, no matter how tightly we installed it—it wobbled every time we drove. The Velcro would peel off easily, the cup holders would either fall out or get unscrewed by my toddler, and there was no recline option, so she couldn’t rest or relax. Now with the Maxi-Cosi Pria, it’s a completely different experience: 1. My daughter tells me every day how comfy she is and so much more content on car rides. 2. The cup holders are built in and secure..they don’t come loose, twist, or fall off. 3. Installation was SO much easier. My husband said it snapped in effortlessly, and it feels solid in our back seat. 4. The seat reclines 3 ways and it has made naps+ long drives way more comfortable for her. The only minor downside is that the cup holders are a bit small, but so far all of her cups have fit. It’s also bulkier than our old seat, but that’s not an issue for us since we only have one child. Honestly, the added comfort and safety are worth every bit of extra space. If you’re going back and forth between Safety 1st and the Maxi-Cosi Pria, choose the Maxi-Cosi. It’s far more secure, better built, and clearly designed with both parent and child in mind. I’m so happy knowing we’ll be using this seat until she outgrows it around age 10. No regrets. This was one of the best upgrades we’ve made! ... show more

    • Good quality and properly sized for a child.
Color: SeaDrift Style: Original
This was my son's choice for us to purchase. Our grandson likes it, and we feel safe. It was a little hard to get it in the Toyota Highlander, but once in, it needs no adjustments.

    • Highly Recommend! We love this car seat!
Color: SeaDrift Style: Original
Bought this car seat for my 15 month old. I did so much research on car seats and their safety features/comfortability and this one was highly rated so I purchased it. She has been using it for a month now and I literally have no complaints! Easy to install the seat, as well as buckle and unbuckle her. She seems to be comfortable buckled in this seat. ... show more

    • decent car seat overall
the car seat overall is a stylish, easy to understand, basic installation-type car seat. however if you have a sedan you might run into issues if you’re trying to use it in the 3rd, most recline, position. the car seat wouldn’t even stay completely locked at position 3 since my cars seats slant (18’ chevy malibu and 14’ ford fusion. both had the same issue) we had to wait to use it until he could sit up on his own. when installing the car seat to get a secure install you do have to remove the bottom portion of the cover to pull the strap tight enough, and i also had my partner push down while doing it because it sure is hard to move that strap, but i guess that’s not really a bad thing. it does seem like a comfortable car seat now that he can sit in it. extremely easy to get baby in and out, the ease of pulling the hardness straps to tighten and loosen over and over is great. the strap holders are definitely a plus. in a few years when switching to forward facing it seems like there will be plenty of legroom. ... show more

    • Love this
10/10 car seat. We did so much research before we landed on this one. The price is fairly reasonable. It isn’t too heavy, but feels sturdy and safe! It’s also easy to install and transfer from my SUV to my husband’s truck. We will be getting another one for our second.

    • He loves it!
He loves it! Bought for my grandson when he comes to visit. I was worried he might not like it as much as his Nuna at home. I like the adjustable recline so he can be comfortable when he sleeps or sit up straighter when he wants to look out the windows. The fabric is plush and comfortable and looks like it will wipe clean easily (although we haven’t needed that yet). It’s easy to safely install in both our vehicles (Audi/Toyota) and the golf cart. Purchased on sale it was a great bargain for all the safety and comfort features it offers. -love the cup holders too! ... show more
